HOSE-CONNECTOR.

Specification of'Letters Patent. Patented Jan. 18, 1910 Applicationfiled March 25, 1909. Serial No. 485,851.

To all whom it may concern:

Be it known that I, LEWEN RINELsON, citizen of the United States,residing at Peoria, in the county of Peoria and State of Illinois, haveinvented certain new and useful Improvements in Hose-Connectors; and

- joining the ends of hose sections; pertaining both to .a mender forpermanently connecting the ends of a broken hose and to a separablecoupling or connector for connecting 'hose sections or for connecting ahose with a faucet, pipe or other fixture.

An object of the invention, therefore, is

to provide a connector in one of its forms' for permanently connectinghose sections and. in another form for connecting them so that they maybe separated from one another.

Another object of the invention is to construct a coupling of simpleform of sheet metal and formed tubing whereby it can be produced at avery low cost.

Another object is to construct a hose coupling of sheet metal and formedtubing whose members though of separate parts can be assembled'as asingle complete article the parts of which are inseparable.

One of the peculiarities of my hose connector is that I am enabled toconstruct all the parts of one of the forms of the device of sheet metaland tubing having the quality of ductility so that the parts may bepreferably assembled and made inseparable. Again, the construction of myconnector of ductile metal is such that certain integral hoseclampingfingers are'arranged' so as to lie close to one another andclamp upon the full periphery of the hose-end, which they clamp and lieflat upon the same, so as to absolutely prevent leakage. And still againthe said fingers are provided with friction points or spurs formedpreferably at an acute angle to the planes thereof so that when inengagement with the hose they offer a great resistance to the movementof the hose in its tendency to leave the coupling.

The means by which these and other advantages are attained will bepointed out in the following specification aided by the drawing in whichFigure 1 is an elevation of a form pf connector as I prefer to constructit. Fig. 2 is a longitudinal section of the same showing a piece of hosein connection therewith.

Fig. 3 is a perspective view of the body of the connector. Fig. 4 is aplan of one of the members of the connector. Fig. 5 is a side elevationof one of the arms or fingers of the member shown in Fig. t and muchenlarged. Fig. 6' is a longitudinal section of the connector as used forconnecting two separable hose sections. Fig. 7 is a cross section of theconnector and a piece of hose showing the relative positions of a seriesof clamping fingers.

A indicates a hollow cylindrical member either formed up from a piece ofsheet metal or cut from drawn tubing or ductile metal and constitutingtheabody of the connector.

B is a ring or collar punched from sheet metal and substantially of theform shown in Figs. 1 and 4. This has a central flat body portion C andfrom ita cylindrical flange D is struck up and this flange is adapted toslip upon and snugly fit the body A. The said collar is dished so as tooverhang the flange and is serrated to create lugs or fingers E whoseextremities are bent \inwardly to producethe friction points or spurs Fto engage the hose and all of which point toward the axis of the bore ofthe ring and each is disposed at an acute angle to the plane of the lugor finger of which it isa part as clearly illustrated in Fig. 5. In thefirst two figures of the drawing I haveshown two of these rings D placedbackt'o back and slipped upon the body or tube A and stationed at aboutthe middle thereof, said rings being held rigidly in position by meansof flanges or ribs G, or their equivalent, although other means ofsecuring the parts together may be resorted to, and I preferablyemploythe well known swaging process as the easiest method of creating saidflanges or ribs or their equivalents.

The tube or body A is preferably expand 1 ed at each end in any desiredmanner'rn order to provide a head or flange A to aid in holding the hosealthough these may not be used. x v

- Fig. 2 illustrates the position of the letter H. This figure shows indotted lines substantially the position of one of the fingers E at eachside of the hose when bent down upon the latter and it is to be notedthat the spurs F, which have been described I as being formed at anacute angle to the fingers, when pressed into the hose extend rearwardlyand inwardly toward the flange D or toward the end of the hose,substantially'in the manner shown, in such a way that resistance to thewithdrawal of the hose results since said spurs constitute what might betermed prevent such withdrawal.

Besides the purpose of utilizing the device as a permanent connectionbetween hose sections there is that of using it to detachably connecttwo pieces of hose or to detachably connect the end of a hose with afaucet or other fixture as has already been stated and Fig. 6 shows themanner of accomplishing the latter object. A tube or body Jcorresponding to A of the other figures is provided as before with itsflanges K corresponding to G of the other figures but in place of havingtwo of the rings B but one is employed. The said member J is providedwith a head or flange M as before while the other end is flared to forma flange N and said end carries an internally threaded member 0 adaptedto turn or swivel on said member J the flared end N being pro vided tohold the member 0 in place. P is alsoone of the tubular bodies havingpart. of its length provided with screw-threadsQ,

to be engaged by the threads of the said member 0. The flanges R of thebody P which correspond with those at G Fig. 2, serve as before to holdthe ring B; said member P being otherwise identical in form with thatdescribed in the earlier figures. It will now be seen that the member Jhaving the swiveled portion 0 may be connected with the member P or witha faucet or other fixture having the proper threads to receive 1t.

In view of the foregoing adaptability of the connector last abovedescribed the device is not therefore confined to the use of two rings Ccombined with the body A since but one of the rings-will act in theimportant capacity stated. The flange N of the tube J could take theplace of the vform of of the earlier figures and if desired the saidmember J could be secured by its flange N, or its equivalent, to a tankor other fixture and a hose could be attached to the other end of thetube by means of the fingers and their spurs.

By providing the cylindrical flange D to fit upon the member A the ringsare given harpoon points that will a larger bearing upon the latter andare stronger and consequently will withstand greater strain than withoutthem.

As formed, the fingers E when bent down into engagement with the hoselie in close relation and cover all of the end of the hose as shown inFig. complete band.

The connector is distinguished from the prior art in having enlargementsor heads at its ends greater in diameter than the body of the tube andin having'the spurs of the fingers lying just behind them so that thehose ends after, being stretched or forced over the said enlargements orheads and contracting to their normal diameters upon the body will beengaged by said spurs. When the hose is stretched beyond its normal interior diameter there is a chance for leakage and it is preferable tohave the fingers of such a length that when bent down upon the hosetheir spurred ends will lie ust behind the heads for instance as shownin Fig. 6 so that the hose will be securely held behind said heads andthat the spurs will bind thehose directly to the tube. In providing astructure that will permit the hose to resume its normal diameter uponthe body after passing over the heads and then binding it behind saidheads by the closely lying 7 forming practically a or adjoining fingers,leakage is entirely prevented and the hose cannot move upon nor leavethe body or tube.

By reason of being constructed entirely of sheet metal my connector isparticularly and peculiarly adapted for a fire-hose since it is strongand of light weight and can withstand an exceedingly heavy pressure.Hose connectors heretofore provided for this particular use havegenerally been castings necessarily heavy in order that they would bestrong and the great weight and consequent high cost prohibited theirgeneral use.

Although it is intimated that ductile metal is preferable it is possibleto cast certain of the parts of the connector and interlock therewithother parts of ductile metal so that a cheaper and more easily madedevice is possible than is the case when a solid or one-piece. castingis used.

In bringing out the invention having the advantages described I seek toinclude the equivalent of what is shown and described.
